Be'it known that 1; CHARLES H. PALMER, of New York city, in the State ofNew York,

which the following is a-specification.

Ieniploy cartridges of copper or brass, and string a; great numbertogether by a flexible connection, to facilitate the feeding of the car-.tridgcs to the firing place by mechanical nieans. 'lhe' cartridges areheld at the moinent of firing'betweerfitwo stout wheels, each of whichis recessed to a depth to receive half the cartridge. Thes'e'ivhcelsstrongly support. the cartridgelatei allyfiwhile the breech is coveredwith astron glybacked disk. Theiiring hammers are'mou'uted'in this disk.

In what I esteem the mostcomplete form of the" invention there are anumber of barrels mounted on a wheel or revolving frame, coinciding insize and form'and in rapidity of revolution with one of the wheels whichcarry the cartridgesg and-which support the-force of the discharge? "Thefcartridges arefired in. succession as rapidly as may be desired, thefiring beingetfected .each through a differ ent barrel until the'fset ofbarrels has made a complete revolutionfwhen the roundof dischargestlirough thesame barrels is again re-. peat'ed, and so on until all thecartridges belonging to that string areused.

The accompanying drawings form a part of this specification,andrepresent what I consider the best means of carrying-out the in vention.

Figur'e lisa general side elevation. Fig. 2 is a transverse section onthe line aas, Fig. 1, showing the novel parts with s'oznuch of the otherparts as is. necessary to indicate their wheel B. n

The cartridges are marked at. Theyare of a length a little greater thanthe thickness of thewheels B C. These are insertedin pockets formed inknitted or woven fabric m, thus for'zning along flexible series equallyspaced. They are stored in a reservoir, A, mounted convenientlyalongside, and are successively brought into position and dischargedthrough point in its circuit. Each cartridge is at the moment of firingclosely confined, and effieiently struck by a suitable firing-pin at theproper moment, the means for shooting all which will now he described. I

D. is a large ring mounted on the spherical. bearing B, with freedom tooscillate slightly thereon. Itsn'jiper edge stands at a little distancein rear of the adjacent faceof the wheel B, while its lower edge pressesfirmly against 90 relation thereto. Fig.3 is a section through thelatter, and forms a firm abutment: for thep'rincipal partsfin the planeof the axes of pressing against the rear-end of each cartridge the twoprincipal wheels. Fig. 4 is a section when the latteris' fired.

The adjacentsurface of the ringD and the small point of the hammer protrudingthrough it form a tight.

abutment at the rear of the cartridge at the moment of firing.

The ring D turns at the same rate as the ring B and its series ofbarrels. Each cartridge as it approaches the point where it isgrippedtightlybetween the wheels 13 is by the abut:

ment-ring D thrust endwise into the slightly counterbored end of thebarrel bth rough which it is to be fired. The front end of thejcartridgeis thin, and, being of copperfor analogous softmaterial, is easilycontracted by being pressed into the barrel. It assumes the conditioneach. wheelfI'and J is a roller, adaptedzjto ref ceive and transmitagreat forcewithfc ut yieldf ing. .Thes'c rollers exactly fillg'thes'pace andf by pressing against each other and-the. wheel B and ring Dhold thejlatter" against yielding to the force of theexplosion. The'-midheight of" each wheel Iand J is formed with spur-gear o-rwithequivalent projections and recesses, which engage the rollers and wheelsreliably together.-' The upperportion isbevel} gear,which engageswithcorresponding bevelgear's on the adjacent faces of the .wheel 13 and ofthe ring D. Rotary motion is communicated to the wheel 1 by means ofthebeveled wheel I, fixed on the low'er end of its -shaft i, and whichis engaged'by a beveled gear-wheel, K, turned by the operator throughthe aidof a crank-handle,K. The operator by turning this handle rotatesthe series of barrels and also the ring D, revolving the lat-- ter inthe-same time as the foriner.

Two deep gfodves are turned in the peripheries of the wheels B O. Inthese are mounted a pair of plows, L, which are fixed on a branchedbracket, A These plows dis- I engage the string of cartridges ifthey-should stick intheir' respective semicircularcavities in either thewheel B'; or' Cafter the firing.

'Af is a curved piece lying concentricto the wheel B, and at.aproperdistance therefrom to hold the cartridges properly in theirsemicircularcavitics on their passage downward to the point of firing.This is mainly impor- E0 tant-'-.;when the last end of a string of canbridges-is being carried down.

N is a light smooth wheel, mounted in a fixed-position,but with libertyto yield-a little by the turning of its supporting-link 0 on thepivot bywhich it is suspended on the bracket A; Thelink is subject to the forceshown in Fig. 5,.' th'e contracted front end serv T There are twowheels, -I the 10f ia sprfng,i;. ).,"arranged asshow n. It urges thewheel N and thestring of cartridges which are ledover it into the properrelations to the wheel B, but with liberty to yield to accommodate anyslight inequalities.

Modifications may b'e-made in the for ms and proportions within widelimits. The num ber of the barrels may be varied. The size of thegear-wheels may be varied so as to' give a greater or less number ofdischarges with each turn of the crank.
